The present invention relates to an aeroplane station mechanically arranged in a comparatively small operating space'to falanding, and a corresponding increase in lifting movement when taking olf and also means to turn the carrier horizontally about a vertical axis in the direction of the wind,

if any, to further facilitate the landing and taking-oill movements. i

For further comprehension of the invention, and of the objects and advantages thereof, reference is had to the following description 'and accompanying drawings, andto the appended claims in which the various features of the invention are more particularly pointed out.

Referring to the drawings in which similar characters of reference designate like parts throughout the several views-z Figure 1 of the drawingsillustrates a side elevational view embodying my invention, and Figure 2 is an end elevational view of the same.

Numeral 5 of the drawings designates a base supported below the ground line 6, and mounted for horizontal turning mbvement upon the base is a 7, provided with a central pivot pin 8 and a series of antifriction supporting balls 9. The table 7 is also provided with bearings 10, in which is mounted the shaftvll, and upon the latter the frame 12 is pivotally supported for adjustment to different inclinations.

Fixed upon the upper members 13 of the frame 12 are a series of bearings 14, in which are rotatably supported a plurality of carrier-wheels 16, indicated by broken lines.

Endless carrier members 17, also shown by broken lines, and preferably comprising well-known silent, high-speed link-chains, are mounted upon the wheels 16. Conventional attachment links, not shown, are provided for the chains for-connecting the transversecarrier-bars 18, and for the su port of the carrier members between the wllieels 16,

the idler wheels 19 are disposed below thel upper runs of the several carriers, and below the lower runs thereof the smaller idler rolls 20 are employed. Between the adjacent upper runs of the several carriers, fixed being secured to the upper members 13 of the frame in any approved manner. The relatively fixed bridges ailord a surface alined with theworking facesof the carriers over which the planes may passin a comparatively even manner. 4

For driving the several carriers in a successively accelerated manner, a motor 22 is fixed to the lower surface of the table' 7, the driving shaft 23 of the motor having, a wheel 24, transmitting power. through chain 25 to a wheel 26, the latter haw'ng an extended hub loosely mounted on the outer end ofthe pivotal shaft 11, a second wheel 27 being fixed to the hub of the wheel 26 and in turn transmitting its power by the chain 28 to a driving wheel 29, fixed upon a driving shaft 15a of the central carrier. From the latter shaft a relatively small wheel 30 drives by achain 31 to a relatively large wheel 32, fixed upon the adjacent carrier shaftlb, thus causing a reduction in the speed of the latter carrier. Also upon the shaft 15e of the central carrier is mounted arelatively large wheel 33 which drives by a chain 34 to a relatively'small wheel 35, fixed upon the adjacent carrier shaft 15d, thus causing the latter carrier to be driven at a relatively higher speed.l By suitably changing the proportion of the several driv.- ing wheels the desired successive acceleration of the carriers may readily be obtained. By changing the speed of the motor, a corresponding change may be made in the velocity of the carriers, and for reversing the latters direction of movement, a similar rebridge members 21 are provided, the same v versa-l of the motor may be made, the several /driving wheels of the carriers being herein shown by dotted lines.

For adjusting the inclination of the carrier frame 12, a drum 36 is provided and mounted in vbearings 37, xed to the lower side of the table 7, the drum being provided with a relatively large driving gear 38, actuated by a pinion. gear 39, fixed to the driving shaftof the motor `40,:the latter being likewise secured to the lower sideof the table. Passing around the drum 36 is a cable 41, the* opposite ends of which are led around the idler wheels 42 and secured Ato the opposite ends of the frame at the points 43, the idler ywheels being loosely mounted on the lower side of the table 7 as shown. By the rotation of the motor 40 in opposite directions, the inclination ofthe frame and carriers may be readilyv adjusted. The cable connections 43 of the frame are equally disposed at opposite sidespof its vboth of landing and taking-off, the advan-Jl tages offered by my improved device` willV pivotal center, and a downward movement at one cable point of' the frame will cause the latter to turn about its pivot point and effect an equal lifting movement' at Vthe pposite cable point, thus acting toequalize the tension at opposite ends of the cable leading from the driving drum 36 and operating to hold the frame against undue movement or vibration from moving loads thereon at all variable points of inclination.

The means herein shown for horizontally turningthetable 7 and the connected frame and carrier, include a :motor 44 supported on the base 5 Vand* carrying a horizontal shaft 45, the latter having at one end 'a bevel pinion 46, engaging a. bevel. gear 47, fixed adiacenti-thelower end of a vertical shaft 48, the lower end of the'latter shaftbein'g carried in a step-bearing 49 of the base, while at its upper end the shaft is mounted in a bearing 50 of the base. Upon the upper end of the vertical shaft 48, is fixed a gear 51, which engages for relative rotation the gear 52, fixed to the lower side of the table 7. By the'rotation'of the motor 44 in .opposite directions the table and-superposed load may be turned about its vertically dis-- posed pivot p in 8.

For the landing of a plane, the platform by the motor 40, and horizontallyturned to a direction'opposed to possible wind pressure by the motor 44; and bythe motor 22 the carriers of the platform are rotated in aA downward direction in opposition to the advancement of the plane, themomentum of the latter up the inclined platform `being quickly arrestedby the gradually accelerated movements of the several carriers through frictional resistance against -theetail drag and the wheel-brake action ofthe plane, and

by the continued rotation vof the carriers the plane may be landed upon the ground i level 6;

A'For taking oft or elevating ia plane in op?j position to possible wind pressure,vthe^'plat form carrier is y'similarly positioned as for landing, except that Vthe carriers 'are rotated initheopposite manner, or in the direction in which the plane is advancing. -AsAthuS o erated the -frictional resistance betweent e quickly moving carriers and the superposed plane, Twilll serve to :quickly pick up the speed of and elevate 'the latter in a com'' be clearly evident.
